December 1, 2007 02:13 PM -

Chicago - The Metropolitan Water Reclamation District of Greater Chicago, one of the nation’s largest water authorities, today announced that it has purchased 30 all-electric, low-speed MILES ZX40 cars as part of its strategy to slash fleet emissions and costs. The acquisition represents the largest purchase of MILES electric vehicles by a government agency. It is estimated that the vehicles will eliminate hundreds of thousands of pounds of greenhouse gas emissions each year in operation.

 

 

The ZX40 hatchbacks will be officially delivered to Water Authority Commissioners on Tuesday, November 27th at 12:00 p.m. during a ceremonial "plug-in," reflecting the fact that MILES cars and trucks are powered by industry-leading batteries that can be charged at any standard household or business outlet.
